Cloud storage security scheme using Dynamic Data Division and Replication

Abstract

Cloud computing is an innovative technology which can utilize in various sector like Internet of Things, Information technology industries, mobile computing and so on. One of the amazing services in cloud is outsourcing the data to a third-party administrative control and also the major reason for security issues. Various security architectures have been proposed by many researchers in past decades. However a high level security framework is still in need for data which is stored in cloud. This research article presents the security enhanced model with data availability through dynamic data fragmentation and replication technique. The dynamic fragmentation is carried out at runtime based on the virtual machine availability and AES encryption method is applied on securing the fragment data. The replication is performed with bee colony optimization approach which selects the best node. Thus improves the better load balance with less number of replicas. This approach enhances the security and does not reveal the original data during the attacks.
